The TMR-2 series is a family of isolated 2W dc-dc converter modules with regulated
output, featuring wide 2:1 input voltage ranges. The product comes in a compact
SIP-8 plastic package with small footprint occupying only 2.0 cm2 (0.3 square in.)
of board space.
An excellent efficiency allows –40° to +75°C operation temperatures at full load.
Further features include remote On/Off control and continuous short circuit protection. The ultra-compact dimensions of these converters make them an ideal solution
for many space critical applications in communication equipment, instrumentation
and industrial electronics.
